Malaria in Turkey: a review of 33 cases.

AIM: To evaluate epidemiologic and clinical features of the patients with malaria followed in our clinic, and to review current status of malaria in our country. PATIENTS AND METHODS: Epidemiologic, clinical, diagnostic, and therapeutic features of 33 patients with malaria (4 female, 29 male, mean age: 28 +/- 11 years, range: 15-60) followed in our clinic between 1981 and 2000 were evaluated retrospectively. Malaria data of our country for 1926-2000 were obtained from Health Ministry. RESULTS: Diagnosis was established by thin smears of blood preparations obtained in the febrile period in all cases. Plasmodium vivax was detected in 26 patients (25 domestic and one imported), and P. falciparum in seven (two domestic and five imported). Sixty-one percent of the patients had the prodromal symptoms of the disease and used various antibiotics. All cases demonstrated the typical pattern of fever with chills. Fever (100%), splenomegaly (91%), hepatomegaly (55%), anemia (70%), leukopenia (48%), thrombocytopenia (48%), a rise in sedimentation rate (100%), and abnormalities in hepatic enzymes (30%) were determined in the patients. Chloroquine + primaquine were given to all patients with P. vivax, chloroquin (for three) or mefloquin (for four) alone were given to the patients with P. falciparum. One patient with P. falciparum died soon after admission, all the remaining recovered. Data from Health Ministry revealed that the most common (approximately 100%) species in our country is P. vivax. Although an eradication program against malaria initiated in 1926 achieved success, it still remains as an important health problem. CONCLUSION: Every febrile patient with a history of travel to the regions where malaria is endemic (tropical regions for the world, southeast regions for our country) should raise the suspicion of malaria. Every country should fight against malaria and global cooperation is essential.

Fever of unknown origin: a review of 20 patients with adult-onset Still's disease.

In this study we aimed to investigate the findings in patients with adult-onset Still's disease (AOSD) admitted with fever of unknown origin (FUO) during the last 18 years in our unit, in order to discover the ratio of such patients to all patients with FUO during the same period, and to determine the clinical features of AOSD in FUO. The number and the aetiologies of the patients with FUO diagnosed between 1984 and 2001, and the clinical features of those with AOSD, were taken from the patient files. The diagnosis of AOSD was reanalysed according to the diagnostic criteria of Cush et al. [11]. The presumed diagnoses before a diagnosis of AOSD was established were also noted. The chi(2) and Fisher's exact tests were used for statistical analysis. We studied 130 patients with a diagnosis of FUO, 36 (28%) of whom had collagen vascular diseases. Of these 36 patients, 20 (56%, 12 female, 8 male, mean age 34 years, range 16-65) had AOSD. Clinical and laboratory findings were as follows: fever (100%), arthralgia (90%), rash (85%), sore throat (75%), arthritis (65%), myalgia (60%), splenomegaly (40%), hepatomegaly (25%), lymphadenopathy (15%), anaemia (65%), neutrophilic leukocytosis (90%), increased erythrocyte sedimentation rate (100%), elevated transaminase levels (65%), a negative RF (100%), and a negative FANA (80%). Antibiotics had been prescribed in 18 (90%) of cases. The presumed infectious diagnoses were streptococcal tonsillitis/pharyngitis (50%), infective endocarditis (four patients), sepsis (two patients) and acute bacterial meningitis (two patients). The presumed non-infectious diagnoses were acute rheumatic fever (three patients), seronegative rheumatoid arthritis (two patients) and polymyositis (two patients). Sixteen patients were followed for a mean duration of 30 months (range 2-59). A remission was obtained with indomethacin in three cases (19%), and with prednisolone in the remainder. Relapse was detected in three cases (19%). AOSD is one of the most frequent aetiologies of FUO. During the diagnostic course of a patient with FUO, a maculopapular rash and/or arthralgia and/or sore throat should raise the suspicion of AOSD. Because the disease has heterogeneous clinical findings, certain bacterial infections (e.g. streptococcal pharyngitis and sepsis) are generally considered and the prescribing of antibiotics is common.

Miliary tuberculosis: clinical manifestations, diagnosis and outcome in 38 adults.

OBJECTIVE: The aim of the study was to determine the clinical, radiographic and laboratory characteristics, diagnostic methods, and prognostic variables in patients with miliary tuberculosis (TB). METHODOLOGY: The records of 38 patients (15 male, 23 female; mean age 41 years, range 16-76 years) with miliary TB from 1978 to 1998 were analyzed. Patients were evaluated also as to whether they presented with a fever of unknown origin (FUO). Criteria for the diagnosis of miliary TB were (i) miliary pattern on chest X-ray or (ii) biopsy or autopsy evidence of miliary organ involvement. Paraffin-embedded tissues with granulomata (n = 15) were re-evaluated for the presence of Mycobacterium tuberculosis DNA by polymerase chain reaction (PCR). RESULTS: Predisposing conditions were present in 24% of the patients. The findings were fever, weakness, night sweats, anorexia/weight loss (100% for each), hepatomegaly (37%), splenomegaly (32%), choroidal tubercles (13%), neck stiffness (11%), altered mental status (8%), anaemia (76%), leukopenia (26%), thrombocytopenia (16%), lymphopenia (76%), pancytopenia (8%) and hypertransaminasemia (55%). Eighteen patients (47%) met the criteria for a FUO. Miliary infiltrates were found on chest X-rays of 32 of 38 cases (84%). In six cases without miliary infiltrates, the diagnosis was made by laparotomy in four cases, and autopsy in two cases. Tuberculin skin test was positive in 32% of cases. Acid-fast bacilli were demonstrated in 37% (16/43), and cultures for M. tuberculosis were positive in 90% (9/10) of tested specimens (predominantly sputum and bronchial lavage). Granulomas were found in 85% (11/13) of lung, 100% (15/15) of liver, and 56% (9/16) of bone marrow tissue specimens. Acid-fast bacilli staining was negative in all (0/21), while PCR was positive in 47% (7/15) of specimens with granulomata. Mortality was 18%. Stepwise logistic regression identified male sex (P = 0.005), non-typical miliary pattern (P = 0.015), altered mental status (P = 0.002) and failure to treat for TB (P = 0.00001) as independent predictors of mortality. CONCLUSIONS: Miliary infiltrates on chest X-ray or FUO should raise the possibility of miliary TB. Therapy should be administered urgently to prevent an otherwise fatal outcome.

Spontaneous pneumothorax: a rare complication of miliary tuberculosis.

Pneumothorax is a rare complication of miliary tuberculosis. In this report, a 25-year old patient developing pneumothorax while on the treatment for miliary tuberculosis treatment is presented and the related literature has been reviewed. Pneumothorax, although rare, should be considered when a patient with miliary tuberculosis develops a sudden, severe pain on either side of the chest with breathlessness. The treatment should be tailored according to the size of pneumothorax either pleural drainage through chest tube or needle aspiration. Meanwhile, antituberculous treatment should be continued without interruption.

A rare complication of miliary tuberculosis: intestinal perforation.

Small bowel perforation is a rare complication of miliary tuberculosis. We report the case of a 21-year old patient who developed a small bowel perforation 70 days after the initiation of adequate tuberculosis treatment. We also present a review of the literature.

Results of hepatitis B vaccination in sarcoidosis.

BACKGROUND: Sarcoidosis is known to be associated with defects in cellular immunity, especially in reference to T helper lymphocytes. Anergy to a tuberculin skin test is most characteristic of this disease. OBJECTIVES: To further the data on impaired immunity, we studied the antibody response to hepatitis B vaccination in patients with sarcoidosis. METHODS: Serologic markers of hepatitis B virus (HBV) (HBsAg, anti-HBs, anti-HBc) were studied in 40 patients with sarcoidosis (32 female, 8 male; mean age: 45 +/- 11 years, range: 25-66 years) with a mean duration of disease of 6 years. While all the markers were negative in 22 patients (55%), 2 had isolated anti-HBc positivity and 16 had both anti-HBc and anti-HBs antibodies. Thirty-five age- and sex-matched healthy subjects were studied as controls. Recombinant HBV vaccines (Genhevac B Pasteur, 20 microg) were administered (at 0, 1, and 6 months) to 16 of the seronegative cases and the controls and antibody titres were measured 1 month after the last dose. The tuberculin skin test was negative in all cases. RESULTS: While none of the vaccinees in the diseased group responded, the control group yielded an antibody response rate of 85. 7% (30/35), with a mean titre of 257.9 mIU/ml. CONCLUSIONS: Patients with sarcoidosis were invariably unresponsive to standard vaccination, while some of the diseased subjects had already mounted a natural antibody response, either before or after the development of the original disease. Cellular immunodeficiency in sarcoidosis could be a suitable model for studying immunological interactions between HBV and the host.

Tuberculous subcutaneous abscesses developing during miliary tuberculosis therapy.

Although rare, paradoxical subcutaneous abscesses may develop during appropriate treatment of miliary tuberculosis. While the pathogenesis of this phenomenon is not clear, some theories have been postulated. A case of a 37-y-old woman diagnosed as having miliary tuberculosis who developed subcutaneous abscesses within the 5 months of antituberculous treatment is described and all 6 similar cases published in English from 1954 to 1999 are discussed.

Value of diagnostic laparoscopy in tuberculous peritonitis.

OBJECTIVE: To assess the safety and efficacy of diagnostic laparoscopy in patients with tuberculous peritonitis. DESIGN: Retrospective clinical study. SETTING: University hospital, Turkey. SUBJECTS: 8 patients (2 women, 6 men; mean age 26 years) who presented with tuberculous peritonitis between January 1994 and January 1996. INTERVENTION: Laparoscopy under local anaesthesia with sedation (the 4 who presented with ascites) and laparotomy (the 4 who presented with an acute abdomen). MAIN OUTCOME MEASURES: Clinical and laboratory findings, biochemical and microbiological analysis of ascites, histopathological examination of specimens, morbidity, and mortality. RESULTS: 4 patients presented with ascites, and 4 with adhesions. Ascites; adhesions between liver and diaphragm, liver and intestines, and intestines and the abdominal wall; miliary nodes on the peritoneal surface; and inflamed haemorrhagic areas on the peritoneum could all be seen at laparoscopy. One of the 8 patients who underwent laparotomy developed a spontaneous enterocutaneous fistula during the early postoperative period. Two of eight patients died, one of an early enterocutaneous fistula and the other of cor pulmonale 3 1/2 months later. The remaining 6 patients survived without complications after antituberculous medical treatment. CONCLUSIONS: Laparoscopy is a safe and accurate method of diagnosis of tuberculous peritonitis.
